A standardized, expandable cap for a newborn infant to reduce heat losses from the skull during the hours immediately following birth. The cap is fabricated by die cutting a sheet of non-woven, spunlaced, synthetic fiber material to create blanks having an arched shape, each blank including an arcuate margin and a straight base, the grain of the non-woven material being normal to the base to render it laterally stretchable. A pair of such blanks are superposed and ultrasonically seamed along a line conforming to the arcuate margin to create the dome of the cap. The cap is completed by puckering the lower rear section thereof to create a shirred zone and ultrasonically welding an elastomeric tape thereacross to provide an expandable cap which when worn adjusts itself to the head of the wearer regardless of head size.
